The present invention discloses a method of automatically detecting and storing the CPU clock frequency in a telecommunications hub. The hub includes a known reference clock for a digital signal processor. A first counter counts the reference clock cycles during the same time period in which a second counter counts the processor clock cycles. The number of processor clock cycles counted is divided by the number of reference clock cycles counted and the result is multiplied by the frequency of the reference clock. The calculated processor clock frequency is compared to a table of available CPU clock speeds and the closest available clock speed is selected. The selected available clock speed is then stored as a variable in RAM for use by all software which uses the processor clock as a base for generating absolute timing signals, such as a one second clock.
